Regex Pattern which Only allow 4 digit

[Radhe]

Hi All.

@Mark Roethof 

I have one variable  (Type - single line text) and I need Regex Pattern which allow only 4 digit (number) in this field

[Willem · Accepted solution]

To match exactly 4 digits:

/^\d{4}$/

^\d{4}$

Not more then 4:

/^\d{0,4}$/

^\d{0,4}$

Hi there,

For exactly 4 digits, this would work:

\d{4}$

or for up to 4:

\d{0,4}$ 

Since it's a variable, please don't go for client script. Use the variable validation regex option.

Hi Radhe,

In regex pattern you can use both way to allow only 4 digit in the field.

To match four digit exactly

 /^[0-9]{4}$/

OR

/^\d{4}$/

please mark helpful if you find it correct.
