1 year, 8 months ago. What's the longest possible worldwide phone number I should consider in SQL varchar (length) for phone. What is the minimum length of a valid international phone number? What is the max and min digits for an international telephone number? (country code + area code + phone number) –. Mobile Country Code(CC) is 1 to 3 digits long.CC Indicates the country to which the number belongs. When a mobile subscriber dials a local mobile phone number, the country code should be omitted. A zero may be substituted for the country code. For dialing outside of the country, the national format is used. I'm trying to write a regular expression to validate US phone number of format (123)123-1234 -- true 123-123-1234 -- true every thing else in not valid. I came up something like Look up E.164. Basically, you store the phone number as a code starting with the country prefix and an optional pbx suffix. Display is then a localization issue. Validation can also be done, but it's also a localization issue (based on the country prefix). For example, +12125551212+202 would be formatted in the en_US locale as (212) 555-1212 x202. (significant) number) N(S)N number length Usage of E.164 number Additional Maximum information length Minimum length 39(NDC) 9 9 Geographic number for fixed telephony services Area code for Upper West region 20 (NDC) 9 9 Non-geographic number for mobile telephony services Mobile Telephony Services assigned to Ghana Telecom 21 and 22 (NDC) I would suggest a varchar for the phone number (since phone numbers are known to have leading 0s which are important to keep) and having the phone number in two fields: Country Code and phone number i.e. for 004477789787 you could store CountryCode=44 and phone number=77789787. however it could be very application specific. I'm trying to create a validation rule for our phone numbers. Every number has 3 parts: Country Code (numerical, min. 1 digit, max 3 digits, starts with '+') Area Code (numerical, min. 1 digit, max 4 digits, cannot start with 0) Number (numerical, no digit limit, cannot start with 0) Examples: +32 12 1234567 +359 123 1234567899 I have a textbox of type number and whenever i typed inside that textbox should ONLY ALLOW numbers [0-9] and it should NOT ALLOW the length of the numbers entered to be more than 8 digits. Eg: 12345678 - Allow 1234 - Dont Allow 1234%^ - Dont Allow aVNFvJ.
