If you need to migrate your Parcelforce account to Royal Mail OBA in Zenstores, follow the steps below.
Please note: this guide assumes you already have a Parcelforce account connected to Zenstores.
- Gather your OBA credentials
Before you start the migration, make sure you have the following details to hand: your Royal Mail OBA account number, the company name associated with your OBA account, the email address you use to log into your Royal Mail OBA, your posting location company ID (a series of numbers associated with each posting location in your OBA), and your posting location address including postcode. If you're unsure of any of these details, contact your Royal Mail account manager.
- Navigate to the migration page
Head to app.zenstores.com/settings/carriers/rmz/parcelforce/check_oba/ in your browser. This is the dedicated migration flow within Zenstores that will guide you through transitioning your existing Parcelforce connection to a Royal Mail OBA. Please note: this guide assumes you already have a Parcelforce account connected to Zenstores.
- Confirm you have a Royal Mail OBA account
You'll be taken to a page asking you to confirm that you have a Royal Mail Online Business Account. Click "Yes, I have an OBA account" to proceed to the next step. If you do not yet have an OBA account, you will need to contact Royal Mail or your account manager to set one up before continuing.
- Enter your OBA credentials and complete setup
On the next page, enter all of your OBA credentials: your account number, company name, email address, posting location company ID, and posting location address. Double-check each field for accuracy, then click "Complete setup". A thank you page will load to confirm your submission — that's everything done on your end.
- Wait for your integration to go live
It normally takes 1–3 business days for Royal Mail to provide Zenstores with your integration details. Once the integration is live, you'll be notified. After it's active, review any shipping rules that previously pointed to Parcelforce services, as these will need updating to reflect the new Royal Mail OBA services.
Frequently Asked Questions
Do I need to remove my old Parcelforce account from Zenstores before migrating?
No, you don't need to remove it manually. The migration flow will handle the transition from your existing Parcelforce connection to the new Royal Mail OBA. Simply follow the steps in the migration guide and the changeover will be managed for you.
Will my shipping history carry over to the new Royal Mail OBA?
Your order history within Zenstores stays intact. However, consignment history from the old Parcelforce system won't carry over to your new Royal Mail OBA — this is a Royal Mail limitation. Historic invoices through parcelforce.com will also no longer be accessible; all billing going forward is managed through your Royal Mail OBA.
Will my shipping rules still work after I migrate?
Not automatically. Any rules that pointed to Parcelforce services will need updating once your Royal Mail OBA is connected. We'd recommend reviewing your shipping rules as soon as the integration is live to avoid any disruption to your fulfilment workflow.
Where do I find my invoices now that parcelforce.com is no longer used?
Invoicing has moved to your Royal Mail Online Business Account. Invoices are no longer accessible through parcelforce.com. If you use both Royal Mail and Parcelforce services, you'll receive a single combined invoice through your OBA.
Can I still send parcels on Parcelforce services after migrating?
Yes, Parcelforce services are continuing. What's changed is the account infrastructure — from August 2025, you access both Parcelforce and Royal Mail services through the same OBA, rather than through separate logins. Your account manager can confirm exactly which services are enabled on your account.
