PAC & Porting questions
PAC stands for Porting Authorisation Code. It authorises a UK mobile network to move the purchased number onto an active SIM on that network.
We send the PAC using the delivery method and order process shown at checkout. If you have not received it within the order estimate, contact support with your order number.
PAC codes are normally valid for 30 days from issue. Use it promptly and follow the receiving network's instructions.
Activate the SIM that will receive the number, then give the PAC to that network through its online account, app, phone service or shop process. The network will confirm the transfer date.
You can generally transfer to a UK network that accepts the number and port request. Compatibility and the receiving network's checks apply, so confirm with them if unsure.
Usually, yes: the receiving network can port the purchased number onto an active SIM. Ask the network how its process treats the temporary number and any existing service.
It is normally replaced when the purchased number transfers. The receiving network can confirm the exact timing and any service changes.
Often, if the receiving network allows a number port onto that plan. Confirm the account requirements, as the network controls the final port and plan terms.
The receiving network sets the expected transfer date. Many ports complete on the date they provide, but account checks or incorrect details can delay the process.
Check that you are using the latest link and the email address or details connected with the order. If it still fails, contact support and include your order number so we can check the link.
An expired PAC cannot normally be used. Contact support to request a replacement; a replacement may require a £35 administration fee.
Ask the network to check the code, number, account details and expiry date. If those details are correct, contact Numbers Market with the network's message and your order information.
The receiving network controls the final inbound port, so contact it first for the transfer status. Contact Numbers Market as well if the PAC or purchased-number details appear incorrect.
