Many of the same issues apply to phone numbers.

When moving countries it can be difficult if not impossible to retain your existing phone number. In some parts of the world moving states means changing your mobile number.

Most telcos “recycle” deactivated numbers after a period of time. This often as short as 6 to 12 months after the owner’s credit expires. I’ve found it increasingly common for a prepaid local SIM number to be tied to a previous owner’s accounts on popular services.

I cannot imagine how it cos be possible in the first place.

I have a French number: +33 and 9 digits. In Germany it is +49 and 10 digits. In Poland +48 and again 9 digits.

How do you imagine porting a national phone number abroad?

I was thinking porting your number to twilio or the like. It’s not supported in all countries.

There are several countries with the same format and country code.

Even if some countries share the same code and format (I know about the US and Canada), this is hardly a universal solution. The vast majority do not.
