OPG (Office de la Poste Guinéenne) is the public postal operator of the Republic of Guinea. It handles domestic and international mail and parcels, including EMS and partner deliveries.

With Ship24, you can track over 1500+ couriers globally such as La Poste, DPD, GLS, etc.
Most OPG numbers follow the UPU S10 format: two letters + nine digits + country code. For Guinea, the code ends with GN. Examples: RR123456789GN, EE123456789GN, CP123456789GN.
For cross-border shipments, OPG hands parcels to partner posts abroad. Inbound items from France (Colissimo) list OPG as the local partner in Guinea. After export, updates may appear next on the destination operator’s system.
For delivery issues, use the contact area on the official OPG website. Provide your tracking number, sender, and destination details to speed up the review.
Paste your OPG tracking number on Ship24 to view updates across handovers and partner carriers in one place. No login required.
Most OPG numbers follow the UPU S10 format: two letters, nine digits, and the country code. For parcels sent from Guinea, the code ends with GN (for example, RR123456789GN). If your code ends with another country, it likely started in that country and later passed through OPG.
This usually means the label was created but not scanned yet, or there is a small typo. Wait for the first acceptance scan, then check again. If nothing changes after a short period, confirm the code with the sender or try universal tracking on Ship24.
GNCKYB is a code used for a sorting center in Conakry. Parcels can stay there briefly during processing before the next dispatch. If your item seems paused at this step, look for the next scan such as departure or customs handover.
Yes. Enter your tracking number on Ship24 to view live status, handover scans, and delivery confirmation. You don’t need to create an account for single lookups.
After export, the destination country’s postal operator usually performs the final delivery. For example, items sent from France may reference Colissimo upstream, while OPG handles local delivery in Guinea for inbound items.
Transit time depends on destination, service level, flights, and customs clearance. Express options move faster than standard mail. Check scans for export, arrival, and customs release to estimate the remaining time.
Use the contact page on the official OPG website and include your tracking number, origin, destination, and a short description of the issue. This helps the support team review the route and provide an update.
