UDI, QR Codes and Electronic Labelling under Nigerian Device Rules

1. Key takeaways

Nigeria’s position on UDI and electronic labelling can be summarised as permitted at the rules layer, required at the GMP layer. The two layers use different verbs, and understanding the difference is what turns a confusing pair of provisions into a clear compliance design.

Rules layer (permitted) — the labelling rules on product identification provide:

• Devices, IVDs and related products must carry a product-specific identification, selectable from 7 forms: batch number, lot number, batch code, lot code, serial number, control number or version number (as applicable);
• The identification must be shown on all packaging components; where it cannot all be shown for reasons of size, the details should be shown on the primary packaging;
• Internationally recognised symbols, the Unique Device Identification (UDI), QR codes and electronic labelling may be used.

GMP layer (required) — DER-GDL-025-00 §12.6: devices must have a UDI to enhance traceability, and the UDI must be indicated on the packaging.

The combined practical conclusion of these 2 provisions: UDI is not optional in Nigeria; QR codes and electronic labelling are expressly permitted supplementary means. Note the asymmetry in tone: for QR codes and electronic labels the rules layer says a company may use them if it wishes, while for UDI the GMP guideline uses mandatory language. A packaging design that treats both as equally optional would fail a GMP inspection even if it passed artwork review, which is why the distinction must be understood at design time rather than discovered at inspection time.

3. Expert insights

Insight one: the rules layer says may apply, the GMP layer says must have — the two do not conflict, but their strength differs. The labelling rules use the wording The Use of … may apply for symbols, UDI, QR codes and electronic labelling; GMP §12.6 states that Devices must have a UDI. Accordingly, electronic labelling and QR codes are optional tools, while UDI is a mandatory element. The rigour applied in dossier review and on-site inspection differs accordingly. In dossier review the reviewer checks whether the label artwork is consistent and complete; in inspection the auditor checks whether the quality system actually produces and controls the UDI, which is a heavier test and the reason to embed UDI in the DMR and DHR rather than only in the artwork file.

Insight two: product-specific identification covers seven forms, from which a company may select one or combine several. Batch number, lot number, batch code, lot code, serial number, control number, version number — the product-specific identification is a set of seven selectable forms. For software devices, the version number is expressly listed as one option, which matches software identification practice. Selecting the appropriate form is a design decision: a high-risk implant may justify serial numbers, while a simple consumable may use a batch number. Whatever the choice, the same form must appear on all packaging components so that traceability chains link up.

Insight three: the fallback rule for small packages is to place the details on the primary packaging. Where the product identification details cannot be shown on all packaging components for reasons of size, the details should be shown on the primary packaging. This differs from the relief logic of Regulation 23(2) for registration numbers — product identification cannot be omitted at any packaging level; it can only be concentrated on the smallest package. The distinction is easy to miss: a team that correctly relies on 23(2) to keep the registration number off the primary pack may wrongly conclude the same for product identification, and that error is exactly what market surveillance looks for.

Insight four: GMP brings electronic displays within the scope of labelling. §12.1 provides that labelling covers device labels, control labels, packaging labels, instructions for use, maintenance manuals, and electronic displays that provide directions or warnings. Consequently, on-screen prompts must be brought under labelling control and change management, with the same discipline as printed artwork: versioned specifications, review records and controlled change. A firmware update that alters a safety warning is a label change, and should pass through the same approval route as a printed artwork revision.

Insight five: Nigeria currently has no standalone UDI database provisions. In the official texts verified for this review, no dedicated provisions on a Nigerian UDI database, issuing agency designation or data submission were found. UDI implementation therefore follows GMP §12.6 and the labelling rules; the specific coding scheme and whether reporting to the Agency is required is a practical estimate and must be confirmed case by case. Companies should not copy the UDI implementation model of another jurisdiction wholesale, but should document their chosen issuing agency and coding structure and confirm acceptance with NAFDAC through their local representative before tooling up.

4. Practical recommendations

1. Treat UDI as a mandatory element in packaging design and record it in the DMR and DHR.
2. Use QR codes and electronic labelling as supplementary means, while retaining paper readability.
3. Concentrate product identification on the primary packaging for small-size packages rather than omitting it.
4. Bring electronic display content into the labelling SOP and change management.
5. Confirm the UDI coding rules and any reporting requirement with the Agency case by case in writing (practical estimate).

The recurring theme is that the mandatory-versus-optional boundary runs through UDI, not through electronic means generally. Budget and project plans should reflect that boundary so that the UDI workstream is never deprioritised in favour of the more visually impressive QR code workstream.

5. Verification checklist

• □ The device carries a UDI indicated on the packaging (GMP §12.6).
• □ Product-specific identification (batch number, serial number, version number, etc.) is shown on all packaging components, or concentrated on the primary packaging under the fallback rule.
• □ QR codes and electronic labels, where used, are consistent with the printed label information.
• □ Electronic display content is under labelling control and change management.
• □ The UDI coding rules and reporting requirements have been confirmed case by case with the Agency (practical estimate).
• □ Label changes have followed the notification or approval procedure of Regulation 6 of the Regulations.

Regulatory information verified as of 29 October 2026. All content cited above was checked against the labelling rules (product identification provision), the GMP guideline (DER-GDL-025-00 §12.1, §12.6) and the Regulations (S.I. No. 42 of 2024, Regulations 19 and 23) as published on the NAFDAC website; no dedicated provisions on UDI coding and reporting were located in the official texts, and the matter is handled as a practical estimate.
