- Understand the January 2026 UPU changes
Royal Mail is making changes to its International Tracked shipping services from January 5th, 2026, as part of UPU (Universal Postal Union) updates. A number of existing service codes are being retired and replaced with new equivalents. These updated services are available to use in Zenstores, so you can continue shipping internationally without interruption.
- Identify which service codes you currently use
Review your current international shipping setup in Zenstores and note which Royal Mail product codes you are using. Cross-reference these against the replacement service codes table to determine whether any of your active services are being retired. Key codes being retired include LLG, MTA, MTB, MTE, MTF, MTG, MTV, LLI, MP0, MP5, MP6, MP9, MTO, OSA, OSB, ITR, and ITV.
- Look up your replacement service code
Use the replacement service codes table to find the new code for each retired service. For example, LLG moves to LLH, MTA moves to MP1, MTB moves to MP4, MTE moves to MP7, MTF moves to MP8, MTG moves to MTK, and MTV moves to MPR. For OSA and OSB, the replacement depends on your format and PC/NPC status — refer to the full changes table for the correct mapping.
- Understand PC vs NPC service distinctions
Some service codes are changing based on whether they are Price Card (PC) or Non-Price Card (NPC) accounts. For instance, OTA (International Tracked On Account) for Letters and Large Letters on PC accounts moves to OTC (International Tracked & Signed On Account), while NPC Large Letter and Parcel formats remain on OTA. Check the full changes table carefully to ensure you select the correct replacement for your account type.
- Note the changes to Signed-only services
Royal Mail is consolidating several Signed-only services into Tracked or Tracked & Signed equivalents. For example, LLI (Signed Zone Sort NPC) moves to LLH (Tracked Zone Sort NPC), MP5 (Signed Zone Sort) moves to MP1 (Tracked Zone Sort), and OSA (International Signed On Account) moves to either OTC or OTA depending on format and account type. This means your shipments will now benefit from full tracking as standard.
- Check cross-border import service changes
If you use cross-border import services, note that ITR (Cross Border - Signed) and ITV (Tracked & Signed - Heavier) are both moving to DEI (Import Cross Border Tracked Parcels). DEJ (Cross Border - Tracked & Signed) is also consolidating into DEI. Update any relevant configurations in Zenstores to use the DEI service code for these shipment types.
- Update your Zenstores shipping rules and defaults
Once you have identified your replacement service codes, update any shipping rules, default carrier settings, or automation rules in Zenstores that reference the retired codes. This ensures your orders continue to be processed correctly after January 5th, 2026, without manual intervention on each shipment.
Frequently Asked Questions
What happens if I keep using a retired service code after January 5th, 2026?
Retired service codes will no longer be valid after the January 5th, 2026 changeover date. Attempting to use them may result in label generation errors or shipments being rejected by Royal Mail. You should update your Zenstores settings to use the replacement codes as soon as possible to avoid disruption.
Why is Royal Mail making these service code changes?
These changes are part of updates driven by the Universal Postal Union (UPU), the international body that coordinates global postal services. Royal Mail is aligning its international service offerings with UPU standards, which includes consolidating some Signed-only services into Tracked or Tracked & Signed equivalents. Full details are available on the Royal Mail website.
Will my shipment costs change when I move to a replacement service code?
Pricing changes depend on your specific Royal Mail contract and account type. In many cases, the replacement services are direct equivalents, but you should check with Royal Mail or review your contract to confirm pricing for the new codes. Contact your Royal Mail account manager if you have concerns about cost implications.
What is the difference between PC and NPC accounts, and why does it matter for these changes?
PC (Price Card) accounts have negotiated pricing agreements with Royal Mail, while NPC (Non-Price Card) accounts use standard published rates. Some service code replacements differ depending on which type of account you hold — for example, OTA for Letters on a PC account moves to OTC, but NPC Large Letter and Parcel formats stay on OTA. Always check the full changes table using your account type to find the correct replacement.
Are the new service codes already available in Zenstores?
Yes, the replacement service codes are available to use in Zenstores from January 5th, 2026. Zenstores is updated to support the new UPU-aligned service codes, so you can update your shipping rules and defaults ahead of the changeover date to ensure a smooth transition.
