JAMB Correction of Data 2026 — Categories of Correction by Source Document

Correction of data on JAMB covers multiple categories — surname spelling, first-name spelling, middle-name spelling, surname-name order, gender, state of origin, local government of origin, multi-profile merge — and each category reads against specific source-document evidence. A surname spelling correction reads against the candidate's NPC birth certificate or NIN slip; a marital name change reads against the marriage certificate; a court-ordered name change reads against the court order and the national-newspaper publication of the name change; a multi-profile merge reads against the candidate's identity-stack data and the JAMB-side records of the duplicate profiles. The operational axis is category-of-correction by source-document-evidence — what is being corrected determines which source documents JAMB reads at the correction step.

This article walks the correction-category taxonomy, the source-document evidence required per category, the eFacility submission surface and the ₦2,500 transaction fee (₦3,500 at some CBT centres inclusive of centre service fee), the one-cycle-per-field cap that restricts repeated corrections of the same field, and the operational notes that distinguish corrections submitted through the open eFacility surface from corrections requiring JAMB State Office attendance.

The three modification surfaces — correction of data, change of course, change of institution — all sit on the same Correction of Data menu on the eFacility portal and share the ₦2,500 transaction fee tier. The structural distinction matters because the operational axis and the downstream consequences differ.

Correction of data operates on the candidate's STATIC biographic and registration record. The fields are fixed at registration and the correction updates the registered value — surname spelling, first-name spelling, surname-name order, gender, state of origin, multi-profile merge. The operational axis is category-of-correction × source-document-evidence — what is being corrected determines which source documents JAMB reads at the correction step. The downstream consequences are documentary: the corrected biographic record propagates to the candidate's CAPS Profile, the candidate's printed UTME result slip and any subsequent JAMB-issued document.

Change of course and change of institution operate on the DYNAMIC course or institution choice. The operational axis is window-and-CAPS-effect — the change happens within a JAMB-defined window per cycle, and the downstream consequence is CAPS re-routing (intra-institution for change of course; cross-institution for change of institution). The change of course walkthrough and the change of institution walkthrough cover the dynamic-choice surfaces in detail.

The asymmetry matters because correction of data does not affect the candidate's institution-side admission decision flow except through the documentary update. A candidate at Admission Offered who corrects a middle-name spelling continues at Admission Offered against the same institution and course; the four-week acceptance grace period continues to run. A candidate at Admission Offered who changes course or institution effectively releases the original offer and surfaces a fresh CAPS state per the admission status walkthrough. The two routes look adjacent on the surface menu; they are structurally different in what they modify and what they trigger downstream.

Date of birth correction is a sub-category of correction of data with its own walkthrough at the DOB correction walkthrough because the multi-source-document framework and the downstream-cascade weight for admission revalidation distinguish DOB correction from the other biographic corrections. This article covers the other biographic corrections in detail.

JAMB activated the 2026 Correction of Data surface on the eFacility portal alongside the change-of-course and change-of-institution surfaces in mid-May 2026, following the 11 May 2026 Policy Meeting. As at publication of this article on 28 May 2026, the surface is operational for 2026 UTME and Direct Entry candidates across the standard biographic correction categories.

Operational availability varies slightly across categories. The surname / first-name / middle-name correction (Correction of Names surface at portal.jamb.gov.ng/changeName.htm) and the date-of-birth correction (Correction of Date of Birth surface at portal.jamb.gov.ng/changeDOB.htm) are typically active through the cycle. Multi-profile merge and heavier corrections (court-ordered name change with national-newspaper publication; corrections involving documentary discrepancy between the candidate's NIN and the candidate's NPC certificate) more typically route through the JAMB State Office at in-person review rather than the open eFacility surface.

A candidate planning a correction during the active CAPS admission period should act early. The corrected biographic record needs to propagate to the candidate's CAPS Profile and the institution-side reading of the candidate's record before the institution's allocation sequence reads the candidate; a correction submitted late in the cycle may not complete in time for the institution's reading. The conservative discipline is to act in the first half of the available correction window.

A candidate reading this article in the 2027 cycle or later should confirm the current cycle's correction-of-data window activation at the JAMB corporate site at jamb.gov.ng before initiating the eFacility transaction. The window is calendar-bound to the cycle though some correction categories run year-round at the JAMB State Office.

Four readers. The 2026 UTME candidate who has discovered a spelling or biographic capture error on the JAMB profile after registration (commonly noticed on the printed UTME result slip or at CAPS login). The Direct Entry candidate in the same posture against a DE registration. The candidate from a prior cycle whose biographic record on the JAMB profile needs alignment with subsequent updates (NIN modification, court-ordered name change, marriage). The parent or guardian of an under-18 candidate, often the operational driver of the correction-of-data decision and the eFacility submission step.

The three-actor architecture matters for correction of data because the JAMB-side correction at eFacility is operationally straightforward but the upstream documentary anchor sits with another registrar — NPC for the birth certificate, NIMC for the NIN, the court for an affidavit or court order, the LGA marriage registry or Federal Marriage Registry for the marriage certificate. JAMB reads against the source document the candidate uploads or presents.

The candidate's identifier framework — the profile code, the JAMB Registration Number, the CAPS Profile and the NIN — shapes the correction logic. The NIN is the identity reference JAMB cross-checks any correction against; a JAMB-side correction submitted against a corrected NIN value propagates cleanly, but a correction submitted before the NIN is corrected may be undone at JAMB's next NIN cross-check:

The correction-of-data taxonomy maps each category to the supporting source-document evidence and the operational route (open eFacility surface or JAMB State Office attendance).

The correction-of-data taxonomy is not exhaustive — JAMB occasionally handles edge cases (cross-cycle data alignment, profile-side variance corrections, prior-cycle registration corrections) that surface at the JAMB State Office documentation desk. The conservative discipline for a candidate uncertain whether the case fits the standard categories is to contact the JAMB State Office in the candidate's state of registration for category-specific guidance before initiating the eFacility transaction or attending the in-person review.

The correction-of-data documentary framework sits alongside the change-of-course, change-of-institution, and date-of-birth-correction documentary postures. A consolidated view helps the candidate place the correction in the wider modification landscape:

Two cross-cluster documentary anchors matter for correction of data. The NPC birth certificate is the primary civil-record evidence for any biographic correction — the civil-documents birth-certificate correction walkthrough covers the NPC-side correction route where the birth certificate itself carries the error. The NIN slip is the identity-stack reference JAMB cross-checks against — the NIN-side name correction walkthrough covers the NIMC self-service correction route where the NIN needs alignment. A candidate whose JAMB record, NIN record and NPC certificate all disagree should sequence the corrections upstream — NPC first, NIMC second, JAMB third — to avoid the JAMB correction being undone at JAMB's next NIN cross-check.

The end-to-end correction-of-data procedure for the open-surface categories (surname / first-name / middle-name spelling, gender, state of origin, LGA of origin) runs through the eFacility portal at https://efacility.jamb.gov.ng/. Heavier categories (marital name change, court-ordered name change, multi-profile merge) route through the JAMB State Office at in-person review.

1. 1
   Open eFacility and sign inOpen the eFacility portal and sign in with the registered email and JAMB password. Where the candidate's email or password is not working, the [JAMB password reset walkthrough](/jamb/jamb-password-reset/) covers credential recovery before the correction submission.
2. 2
   Open the Correction of Data menuOn the eFacility dashboard, open the Correction of Data menu. The menu surfaces three modification options — Change of Course / Institution, Correction of Names, Correction of Date of Birth. For surname / first-name / middle-name corrections, select Correction of Names. For other biographic corrections, the surface routes through the broader Correction of Data submission form.
3. 3
   Select the specific correction categoryThe surface presents the candidate's current registered value for the chosen field. Enter the corrected value. The surface asks for confirmation against the supporting source-document the candidate is using as evidence.
4. 4
   Confirm the corrected value carefullyBio-data fields are typically restricted to one correction per cycle. Verify the corrected value against the supporting source-document carefully before submitting — a second correction of the same field within the cycle is operationally restricted. Re-read the spelling, the order, the value against the source document.
5. 5
   Pay ₦2,500 through the eFacility payment surfaceThe transaction fee on the open eFacility surface is widely reported at ₦2,500 per correction across 2026 cycle coverage; some CBT centres add a service fee bringing the total to ₦3,500. Payment is through the standard eFacility payment surface (card, bank transfer, or Remita).
6. 6
   Submit the request and watch the candidate profileSubmit the correction request after payment confirms. The candidate's eFacility profile updates against the corrected value typically within 24 hours to 7 working days per the 2026 cycle coverage. The corrected biographic record then propagates to the CAPS Profile, the printed UTME result slip and any subsequent JAMB-issued document.

The eFacility surface is the canonical route for the open-surface categories. The JAMB State Office route applies for the heavier categories — the candidate attends the State Office with the original supporting documents (NPC birth certificate, NIN slip, marriage certificate, court order, national-newspaper publication, sworn affidavit, secondary school O-Level certificate), the documentation desk verifies the documents against the candidate's profile, and the correction is processed at the State Office desk with the typical few-weeks reflection timeline.

The open eFacility surface handles the cleanest categories — a spelling correction with the NPC birth certificate supporting the corrected value, a state-of-origin correction with the NIN slip supporting the corrected value. The JAMB State Office route handles the cases where the documentary stack is heavier or the JAMB-side review needs in-person engagement.

Cases that more typically route through the State Office include:

• Marital name change where the marriage certificate carries the new surname and the candidate wants the JAMB record to reflect the marital name. The State Office reviews the marriage certificate, the NPC birth certificate carrying the maiden name and the sworn affidavit before processing.
• Court-ordered name change where the candidate's name was legally changed through court order after the original JAMB registration. The State Office reviews the certified true copy of the court order, the national-newspaper publication of the name change and the sworn affidavit.
• Multi-profile merge where the candidate inadvertently created multiple JAMB profiles in different cycles. The State Office runs the merge at JAMB's database side; the open eFacility surface does not handle merges.
• Documentary discrepancy between the JAMB record, the NIN, and the NPC certificate where the three records do not agree and the JAMB-side correction needs the State Office's documentation desk to reconcile the variance.
• Cross-cycle correction cases where the candidate's prior-cycle JAMB registration needs alignment with subsequent cycle data.

The State Office route is operationally heavier than the open eFacility route — the candidate attends in person with the original documents, the documentation desk reviews, the correction is processed at the desk, and the timeline runs to several weeks rather than a few days. The fee posture on the State Office route is largely the same ₦2,500 per correction, paid at the State Office payment desk or referenced from a Remita slip generated against the candidate's profile.

The JAMB State Office in the candidate's state of registration is the typical venue; in special cases (court-ordered name change with cross-state implications, prior-cycle reconciliation involving JAMB headquarters records) the JAMB headquarters at Bwari Abuja handles the case. The State Office routes JAMB-headquarters cases through the State Office's forwarding desk; the candidate's first stop is the State Office regardless of where the case is ultimately processed.

The JAMB Correction of Names portal page (portal.jamb.gov.ng/changeName.htm) and the 2026 cycle coverage by Studentsdash, Myschoolgist and Campus Cybercafe converge on the one-cycle-per-field cap for biographic corrections — the candidate can typically correct a given bio-data field once per cycle. A second correction of the same field within the same cycle is operationally restricted regardless of the candidate's willingness to pay a second ₦2,500 transaction fee.

The cap has practical implications:

• The corrected value must be the right value the first time. A surname correction submitted as ADEYEMU but actually requiring ADEYEMU-OLATUNJI cannot be corrected again later in the cycle to the longer form. The candidate's only route is to wait for the next cycle's registration and register the correct surname, or to attend the JAMB State Office for exceptional in-person review.
• The supporting source-document evidence must support the specific corrected value submitted. A correction submitted with NPC birth certificate evidence supporting one value but where the candidate inadvertently entered a slightly different value on the eFacility surface is the candidate's own input error; the State Office may handle the exceptional case but the open surface treats the submission as binding.
• Multiple distinct fields can each be corrected once per cycle. A candidate who needs to correct surname AND middle-name AND state of origin treats each as a separate correction transaction at ₦2,500 per correction. The cap is per-field, not per-candidate.

The careful-verification discipline is to read the corrected value back against the supporting source-document twice before pressing submit — once before payment, once after payment confirms but before the final submit. A second human reading (parent or guardian for under-18 candidates) catches the typos a tired candidate misses. The ₦2,500 per correction is enough money to justify a thirty-second double-check.

Four issues surface most often around correction of data.

• Correction reflects on the eFacility profile but the CAPS Profile and the printed UTME result slip continue to show the old value. The JAMB-side propagation between the eFacility profile and the downstream surfaces takes time — typically within the same 24-hour to 7-working-day window but occasionally longer. The candidate's route is to wait at least a full working week before escalating; the eFacility candidate-help link with the transaction reference is the first escalation surface, the JAMB State Office is the in-person route.
• JAMB cross-check against NIN flags the correction as inconsistent with the NIN record. The most common cause is the NIN itself carrying the wrong value — JAMB reads against the NIN that issued the candidate's profile code, and a JAMB-side correction against an uncorrected NIN may be unwound at the next cross-check. The route is to correct the NIN first at the NIMC self-service modification portal at selfservicemodification.nimc.gov.ng per the [NIN-side correction walkthrough](/nin/how-to-correct-nin-name/), then re-submit the JAMB correction against the corrected NIN.
• Candidate entered the wrong corrected value on the eFacility surface and the one-cycle-per-field cap restricts a second correction. The candidate's route is the JAMB State Office at in-person review with the original supporting documents and a written explanation of the input error. The State Office handles exceptional cases at documentation-desk discretion; the open eFacility surface treats the original submission as binding. The cycle-side route is to wait for the next cycle's registration and register the correct value.
• Heavier correction (marital change, court-ordered change, multi-profile merge) is submitted through the open eFacility surface and the submission stalls. The open surface handles the cleaner spelling and value corrections; heavier corrections route through the JAMB State Office at in-person review. The candidate's route is the eFacility candidate-help link explaining the case and a parallel JAMB State Office attendance with the original documents.

A candidate stuck on any of the above has the eFacility candidate-help link as the first escalation surface and the JAMB State Office as the in-person route. The correction-of-data mechanic is operationally stable for the open-surface categories with clean documentary evidence; complications typically arise where the documentary stack is heavier, where the NIN side has an uncorrected variance, or where the candidate's input on the eFacility surface does not match the supporting source-document precisely.

Correction of data sits adjacent to several other JAMB and cross-cluster surfaces:

• JAMB date of birth correction walkthrough — the DOB-specific correction surface with its multi-source-document framework and downstream-cascade implications for admission revalidation.
• JAMB name correction walkthrough — the name-side correction detail, with the multi-cluster mirror context for cross-cluster name-alignment.
• JAMB change of course walkthrough — the intra-institution course-change surface, structurally distinct from correction of data by operating on dynamic course choice rather than static biographic data.
• JAMB change of institution walkthrough — the cross-institution change surface with CAPS re-routing, structurally distinct from correction of data on the same axis as change of course.
• JAMB profile code walkthrough — the candidate-identifier framework reference; the NIN that issued the profile code is the identity reference JAMB cross-checks any correction against.
• JAMB eFacility reference — the candidate-side portal hosting the Correction of Data menu where most correction categories sit.
• NIN-side name correction walkthrough — the upstream NIMC correction route where the NIN itself needs correction before the JAMB-side propagation.
• Civil-documents birth-certificate correction walkthrough — the upstream NPC correction route where the birth certificate itself carries the error and the correction needs to flow through the identity stack.

The correction-of-data fee, procedure and category guidance quoted in this article reflect 2026 cycle coverage by Eduvantage, Studentsdash, JAMB News Today, Myschoolgist, Smart SMS Solutions, Campus Cybercafe and MediaNGR alongside the JAMB Correction of Data and Correction of Names portal pages. Some sources cite a ₦3,500 inclusive-of-CBT-centre figure where the candidate uses a centre rather than the open eFacility surface; the ₦2,500 figure is the open-surface standard. Confirm at the eFacility payment step before settlement. The correction-of-data mechanic has been stable across recent cycles; cycle-by-cycle JAMB-side process changes are possible.
