I am using the is_e164() function to validate the number we receive, and I come to see that the number +555 was accepted.... After some googling it looks like(it is not very clear though) that 7 digits are the minimum we could have for e164 numbers but after checking the source code, I saw it accepts anything starting with + and having between 2 and 16 numbers. So is it really valid to have a number with just 2 digits? What is the case?
Hello Patrick,
I think the implementation was done with a pragmatic approach, to make sure that we don't reject numbers that are used in the field. The ITU standard Amendment A mentions the possibility to use national short numbers, for example. The standard mentions that the maximal length should be 15, but I think in this case this was also implemented a bit more relaxed.
The original implementation from the enum module allows even longer numbers, I will check if this should be synchronized.
Best regards,
Henning
