Regex to select eight digit number

Help
1

Hi Everyone,

I want to select an eight digit number without any space or hyphen even if it presents. In the below snippet i want to select only 01299100 and regex should not take the number 00210000 by excluding - or space.

e.g toll number: +1-000-000-000

toll free number for usa: 1-000-000-0000

toll free number: 0008-00210000

sr01299100
sr 01299100

Thanks,
Ulaga

\b[0-9]{8}\b

@Tiberiu_Niculescu Thank you. This is the same I used but it selects this number “00210000” also. I don’t want it get selected. this number is actually a toll free number : 0008-00210000

Hey @Boopathi

just use this one - \b[1-9]{8}\b

Thank you but It does not match and getting this message when tried to use in https://regex101.com/

In simple

toll free number: 0008-00210000

sr01299100
sr 01299100

I want only “01299100” from the above string

6

try this one (?:^|\s|$)[0-9]{8}(?:^|\s|$)

Thank you but this also selects 00210000. Want to exclude this number 00210000 based on the - symbol used before it.

Then you could use a substring(1,8) to get only the number. I’m not that good at regex.

@Boopathi
Use ((?<=[a-zA-Z ]+)[0-9]{8}) means 8 digits after characters or space

Hey @Boopathi

Check it out -regex101: build, test, and debug regex

and you can use below regex pattern - (?<=[\w\s])\d{8}
