To ensure a successful transaction and to avoid a duplicate sale, it is important to modify the number prefix if you are planning to continue with a similar transaction as before. Follow the simple instructions below:

Check Previous Transaction

Before proceeding, confirm if the current transaction is a duplicate sale.

Modify the Number Prefix

If the previous transaction had a prefix of “639,” change it to “09.” Alternatively, if the previous transaction had a prefix of “09,” change it to “639.”

For instance, if the previous number was “639123456789,” modify it to “09123456789.”

Note: If you are not continuing with a similar transaction, there is no need to make any changes to the number prefix. Proceed with your transaction as usual.
