In this regex tutorial, we will learn to validate international phone numbers based on industry-standard notation specified by ITU-T E.123The rules and conventions used to print international phone numbers vary significantly around the world, so it’s hard to provide meaningful validation for an international phone number unless you adopt a strict format. It is used by a growing number of domain name registries, including .com, .info, .net, .org, and
Fortunately, there is a simple, industry-standard notation specified by ITU-T E.123. The significance of this is that EPP-style international phone numbers are increasingly used and recognized, and therefore provide a good alternative format for storing (and validating) international phone numbers. NNNNNNNNNNx EEEE, where C is the 1–3 digit country code, N is up to 14 digits, and E is the (optional) extension.
sometimes the answer to a problem is to approach it differently. The following regex will catch widely used number and character combinations in a variety of global phone number formats: Positive: 42 555.123.4567 1-(800)-123-4567 567 7(926)1234567 (926) 1234567 792612345567 9261234567 1234567 123-4567 123-89-567 469 123 45 67 89261234567 8 (926) 1234567 926.123.4567 415-555-1234 650-555-2345 (416)555-3456 2 4035555678 1 4 Negative: 926 3 4 8 800 600-APPLE Original source: I believe the Number:: Phone:: US and Regexp:: Common (particularly the source of Regexp:: Common:: URI:: RFC2806) Perl modules could help.
I have to say that the validation function 'valid_int_phone_number($phonenumber)' in inc has many issues and doesn't work as proposed.
So we’ve put a lot of effort into these background matters, confident that you’ll read it before you start or when you get frustrated by your use of regular expressions and want to bolster your understanding.
Only works for countrycode 1 and 44 (ca and uk) -- Validation fails for all other countrys, always.
The original problem is trying to handle phone number validation because it was trying to handle all the possible formatting options. Here's a regex for a 7 or 10 digit number, with extensions allowed, delimiters are spaces, dashes, or periods: ^(? Here's what I used for a client project recently, where we had to convert all phone numbers in any format to tel: links.
Rather than try to solve all that, take the input and "pre-strip" it of all formatting fluff until you have just the "number". How are extensions (e.g., 111-222-3333 x 44444) going to be handled? So far, it's been working with everything they've thrown at it, but if errors come up, I'll update this answer.
If I could choose, I would prefer to receive reminding SMS.
It’s more interruptive, but reminders should work this way :) In the world there is nearly 5 billions mobile phone users.
