The literal “x” character is required only if an extension is provided. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).

If you enter a number then a space it works, but if you just input a space, it does not work. You're right on time again Sonu Kapoor, thanks again! It's very hard to find the right answer on this site, as only a handful of posters actually post the correct answer with no missing (essential) information.

You need TWO validator controls to ensure only numeric values are entered.

The last question mark is to make country code optional. The leading plus sign and the dot following the country code are required.

where C is the 1–3 digit country code, N is up to 14 digits, and E is the (optional) extension.

I'll update this if I get around to create a regular expression based on the ITU E.164 numbering.

I guess that's the starting point to your regular expression.

Anyway, we will discuss both methods in this tutorial. We don’t know what will user enter in the input fields. Sometimes you may want to allow `-` in phone numbers. Let’s see how `filter_var` function reacting to it. In international formatting, you need to allow sign with country code. Let’s take 1-202-555-0170 and see what output does filter_var gives to it. Next, we will see how do we validate phone numbers using Regular Expressions A lot of beginner level developers find regular expression is difficult. [0-9] $ You can use this to validate whether a user has entered a number (2) or number with decimals (2.45453). I would have expected the Range Validor to work, but it doesn't. Taffy Hi I have a telephone number field which may accept following format 46 85 90 35 518 358 26 38 03 85 01993 831841 46 303 778 350 44(0)1344 621681 (01945) 871007 I need a regular expression to validate above field.. Ok If you want to match a floating point numbers use this ^[0-9]*\.?Hey, I'm looking for the formula for a validator that will accept numbers only. I read this post: But, this examples stills allows spaces. use this ^[0-9] $ You can also use compare validator for this with the following properties: Operator="Greater Than Equal" Type="Integer" Value To Compare="0" // or whatever value you want Or You can use this expression: Validation Expression="^[0-9]*$" hi taffylewis, check this post here i explained clearly how to restrcit user to enter only numbers in textbox using javascript. But if you only want to match whole numbers like 2, 3, 333, 545 etc.
