whatsapp api uses 13 digit format for mexico, phonenumber does not recognize it

[joseponzo]

For Mexico, WhatsApp API sends (webhook) you a message with the 13-digit number format, starting with +521. But PhoneNumber only recognizes the 12-digit format +52. It is a native feature of WhatsApp API. Just for them, it is necessary to accept both options for Mexico. regards

Could you give an example of a specific number and Python library call that gives the wrong result?

Also, can you confirm that the Python code gives a different result than the upstream Java code?
