I need to validate uk numbers
Below are sample type of number
01457 341235
0229 111111
+1213 3133143
Optional Plus should be allowed at first postion only
Using this regex but not working
^(?:\W*\d){11}\W*$
An actual UK phone number will start with 0 or +44 (the latter being the UK country code), or possibly just 44, followed by nine or ten digits. A regex to capture that would look something like:
^(?:0|\+?44)(?:\d\s?){9,10}$
In this regex, I have allowed the digits to be separated by spaces in any way, because there isn't a single standardized way of breaking down the numbers. You could further narrow this down to certain allowed groupings, if you like, but it would greatly increase the complexity of the regex.
Your question implies you might want something broader or different. As some of your examples aren't valid UK numbers (+1213 3133143, 12345 123456).
You could use something like this to simply match between 10 and 12 digits, with arbitrary spacing, possibly preceded by a +:
^\+?(?:\d\s?){10,12}$
I have written a VIN validation RegEx based on the http://en.wikipedia.org/wiki/Vehicle_identification_number but then when I try to run some tests it is not accepting some valid VIN Numbers.
My RegEx:
^[A-HJ-NPR-Za-hj-npr-z\\d]{8}[\\dX][A-HJ-NPR-Za-hj-npr-z\\d]{2}\\d{6}$
VIN Number Not Working:
1ftfw1et4bfc45903
WP0ZZZ99ZTS392124
VIN Numbers Working:
19uya31581l000000
1hwa31aa5ae006086
(I think the problem occurs with the numbers at the end, Wikipedia made it sound like it would end with only 6 numbers and the one that is not working but is a valid number only ends with 5)
Any Help Correcting this issue would be greatly appreciated!
I can't help you with a perfect regex for VIN numbers -- but I can explain why this one is failing in your example of 1ftfw1et4bfc45903:
^[A-HJ-NPR-Za-hj-npr-z\d]{8}[\dX][A-HJ-NPR-Za-hj-npr-z\d]{2}\d{6}$
Explanation:
^[A-HJ-NPR-Za-hj-npr-z\d]{8}
This allows for 8 characters, composed of any digits and any letters except I, O, and Q; it properly finds the first 8 characters:
1ftfw1et
[\dX]
This allows for 1 character, either a digit or a capital X; it properly finds the next character:
4
[A-HJ-NPR-Za-hj-npr-z\d]{2}
This allows for 2 characters, composed of any digits and any letters except I, O, and Q; it properly finds the next 2 characters:
bf
\d{6}$
This allows for exactly 6 digits, and is the reason the regex fails; because the final 6 characters are not all digits:

Dan is correct - VINs have a checksum. You can't utilize that in regex, so the best you can do with regex is casting too wide of a net. By that I mean that your regex will accept all valid VINs, and also around a trillion (rough estimate) non-VIN 17-character strings.
If you are working in a language with named capture groups, you can extract that data as well.
So, if your goal is:
Only to not reject valid VINs (letting in invalid ones is ok) then use Fransisco's answer, [A-HJ-NPR-Z0-9]{17}.
Not reject valid VINs, and grab info like model year, plant code, etc, then use this (note, you must use a language that can support named capture groups - off the top of my head: Perl, Python, Elixir, almost certainly others but not JS): /^(?<wmi>[A-HJ-NPR-Z\d]{3})(?<vds>[A-HJ-NPR-Z\d]{5})(?<check>[\dX])(?<vis>(?<year>[A-HJ-NPR-Z\d])(?<plant>[A-HJ-NPR-Z\d])(?<seq>[A-HJ-NPR-Z\d]{6}))$/ where the names are defined at the end of this answer.
Not reject valid VINs, and prevent some but not all invalid VINs, you can get specific like Pedro does.
Only accept valid VINs: you need to write code (just kidding, GitHub exists).
Capture group name key:
wmi - World manufacturer identifier
vds - Vehicle descriptor section
check - Check digit
vis - Vehicle identifier section
year - Model year
plant - Plant code
seq - Production sequence number
This regular expression is working fine for validating US VINs, including the one you described:
[A-HJ-NPR-Z0-9]{17}
Remember to make it case insensitive with flag i
Source: https://github.com/rfink/angular-vin
VIN should have only A-Z, 0-9 characters, but not I, O, or Q
Last 6 characters of VIN should be a number
VIN should be 17 characters long
You didn't specify which language you're using but the following regex can be used to validate a US VIN with php:
/^(?:([A-HJ-NPR-Z]){3}|\d{3})(?1){2}\d{2}(?:(?1)|\d)(?:\d|X)(?:(?1)+\d+|\d+(?1)+)\d{6}$/i
I feel regex is not the ideal validation. VINs have a built in check digit. https://en.wikibooks.org/wiki/Vehicle_Identification_Numbers_(VIN_codes)/Check_digit or http://www.vsource.org/VFR-RVF_files/BVINcalc.htm
I suggest you build an algorithm using this. (Untested algorithm example)
This should work, it is from splunk search, so there are some additional exclusions**
(?i)(?<VIN>[A-Z0-9^IOQioq_]{11}\d{6})
The NHTSA website provides the method used to calculate the 9th character checksum, if you're interested. It also provides lots of other useful data, such as which characters are allowed in which position, or how to determine whether the 10th character, if alphabetic, refers to a model year up to 1999 or a model year from 2010.

Hope that helps.
Please, use this regular expression. It is shorter and works with all VIN types
(?=.*\d|[A-Z])(?=.*[A-Z])[A-Z0-9]{17}
I changed above formula by new below formula
(?=.*\d|=.*[A-Z])(?=.*[A-Z])[A-Z0-9]{17}
This regular expression consider any letter but at leats one digit, max 17 characters
How do I create a regex that matches telephones with or without spaces in the number?
I have found:
^\+?\d+$
From another post but how do I modify that to allow 0 or more spaces in the number?
The first thing you need to think is the exact format you want for phone numbers containing spaces. Eg:
+535 233 4444
Is that one OK? It means divided like: 3 3 4. You can adapt the following regex to your needs:
^\+?\d{3}\s?\d{3}\s?\{d}{4}$
Just change the quantifiers ({3}, {4}, etc) to change the group lengths.
This is one example:
/^(?:\s*\d{3})?\s*\d{3}\s*\d{4}\s*$/
There's a lot of ways to match telephone numbers (and a lot of valid telephone formats). Here's a simple regex to match "5555555555", "555 555 5555", "(555) 555-5555", "555-555-5555", or "555.555.5555"
^(?\d{3})?( |-|.)?\d{3}( |-|.)?\d{4}$
I'm trying to match exactly the following format:
+639201112222
09201112222
and this is all Ive tried so far:
(\+63|0)?\d{10}
the problem is that it match 2920111222 in 29201112222. How can i create a pattern that will match only the formats below?
+63XXXXXXXXXX
0XXXXXXXXXX
+63 or 0 plus 10 digit number only
where X are all digits from 0-9.
Thank you.
You want to do:
((\+63)|0)\d{10}
A regex for various phone number combinations (just quickly used rubular.com for this):
/(^0|[89]\d{2}-\d{3}\-?\d{4}$)|(^0|[89]\d{2}\d{3}\d{4}$)|(^63[89]\d{2}-\d{3}-\d{4}$)|(^63[89]\d{2}\d{3}\d{4}$)|(^[+]63[89]\d{2}\d{3}\d{4}$)|(^[+]63[89]\d{2}-\d{3}-\d{4}$)/
Validates:
0917-411-1111
0917-4111111
917-411-1111
9174111111
+63917-411-1111
63917-894-3454
639172342345
+639174111111
Here's a solution:
http://jsfiddle.net/kZMRx/
I'm looking for a custom RegEx expression (that works!) to will validate common phone number with area code entries (no country code) such as:
111-111-1111
(111) 111-1111
(111)111-1111
111 111 1111
111.111.1111
1111111111
And combinations of these / anything else I may have forgotton.
Also, is it possible to have the RegEx expression itself reformat the entry? So take the 1111111111 and put it in 111-111-1111 format. The regex will most likely be entered in a Joomla / some type of CMS module, so I can't really add code to it aside from the expression itself.
\(?(\d{3})\)?[ .-]?(\d{3})[ .-]?(\d{4})
will match all your examples; after a match, backreference 1 will contain the area code, backreference 2 and 3 will contain the phone number.
I hope you don't need to handle international phone numbers, too.
If the phone number is in a string by itself, you could also use
^\s*\(?(\d{3})\)?[ .-]?(\d{3})[ .-]?(\d{4})\s*$
allowing for leading/trailing whitespace and nothing else.
Why not just remove spaces, parenthesis, dashes, and periods, then check that it is a number of 10 digits?
Depending on the language in question, you might be better off using a replace-like statement to replace non-numeric characters: ()-/. with nothing, and then just check if what is left is a 10-digit number.
