If you want a more precise one and a more forgiving one for different typing preferences, you can use this
(\+254|^){1}[ ]?[7]{1}([0-3]{1}[0-9]{1})[ ]?[0-9]{3}[ ]?[0-9]{3}\z

If you want to validate +2547, or +2541, or just 07 or 01,

^(+254|0)([7][0-9]|[1][0-1]){1}[0-9]{1}[0-9]{6}$

@Code-Buddie how about this one to support 07xxx and 01xx numbers ^(+254|0)([17][0-9]|[1][0-1]){1}[0-9]{1}[0-9]{6}$

it still works
RegExp regExp = new RegExp(
r"^(+254|0)([7][0-9]|[1][0-1]){1}[0-9]{1}[0-9]{6}$",
caseSensitive: false,
multiLine: false,
);

The python code snippet below validates a kenyan mobile phone number (For all service providers). The following 8 formats are valid. Any other format is invalid.

  1. 07XXXXXXXX
  2. 2547XXXXXXXX
  3. 7XXXXXXXX
  4. +2547XXXXXXXX
  5. 01XXXXXXXX
  6. 1XXXXXXXX
  7. +2541XXXXXXXX
  8. 2541XXXXXXXX
    validating_kenyan_number
    If the value of valid is None, then the mobile number provided doesn't match any of the formats listed above.

right now we have number starting with both 07 and 01, what's the regex for that?

`import re

pattern = r'^(+254|0)([7][0-9]|[1][0-1]){1}[0-9]{1}[0-9]{6}$'

Test the pattern

phone_numbers = [
"+254712345678",
"0712345678",
"0112345678"
]

for number in phone_numbers:
if re.match(pattern, number):
print(f"{number} is a valid phone number.")
else:
print(f"{number} is not a valid phone number.")
`

the phone input am using holds the phone to state in the format +254 712 345678, it has refused to pass most regex. can it be the spacing. please provide me with a regex that validates this exactly as it is, thanks

Can I also ask a question because I have some doubts about it? Last semester, I was under immense pressure to finish my dissertation. I found https://ukwritings.com/write-my-dissertation and they came to my rescue. Their writers are experts in various fields, and they delivered a well-structured dissertation on time. The service was worth every penny, and I couldn't be happier with the result.

Works with Java, but you can probably simplify them further.

Safaricom (\\+?254|0)?([7][0129][0-9]|[7][4][0123568]|[7][5][789]|[7][6][89]|[1][1][012345]){1}[0-9]{6}
Airtel (\\+?254|0)?([7][38][0-9]|[7][5][0123456]|[7][6][2]|[1][0][012345678]){1}[0-9]{6}
Telkom (\\+?254|0)?(77[0-9]){1}[0-9]{6}
Faiba (\\+?254|0)?(747){1}[0-9]{6}
Equitel (\\+?254|0)?(76[3456]){1}[0-9]{6}
