You might also want to have a look at the “phonenum” module...

Thanks for the replies guys!
I will probably add a length test to invalidate too short numbers!
By the way, I had a quick look in the ITU recommendation (
https://www.itu.int/rec/T-REC-E.164/en) and looks like the short numbers
are for local purposes only being part of the "Non-ITU-T E.164 numbers"
section, so I guess the function should return false in this case. Also it
seems the + sign is recommended but not mandatory for a E.164 number, which
is quite confusing.....
Kind regards,
Patrick Wakano

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
