Why does the tool say my number is too short, and why did it accept one that was missing digits?
The tool counts every digit including the country code and rejects fewer than 8 or more than 15, the general limits for international numbers. It does not know that a Saudi mobile must be exactly 12 digits, so it accepted +966 50 123 as a valid shape even though it is incomplete. The limit catches gross errors; a missing digit is yours to spot.
Where 8 and 15 come from
A full international number, country code plus national number, is at most 15 digits under the international standard, so the WhatsApp link generator rejects anything longer. The minimum of 8 is a practical floor the tool itself sets for a country code plus a national number; it is not a figure from the standard. Both limits apply to every country; neither is tailored to one.
The cases the tool rejects
- 9665012: seven digits, so you get 'The number is too short: 7 digits', with a reminder that the minimum is 8.
- 9665012345678901: sixteen digits, so you get 'The number is too long: 16 digits'.
Too short usually means you copied only part of the number, or you picked a country code and have typed only a few digits so far. Too long usually means two numbers ran together, or a country code appears twice in front of a long number.
The case that slips through
Type +966 50 123 and stop. That is eight digits: 96650123. The length is inside the limits and it does not start with 0, so a link is created. But a Saudi mobile in international form has 12 digits, so four are missing. The reverse also happens: +966 50 123 45678 9 is fourteen digits and is accepted, although it is two digits longer than the real thing.
Why not check each country's length? Because lengths vary within a single country between mobiles, landlines and special numbers, and they change over time. A per-country rule would wrongly reject genuine numbers. The tool checks what is fixed and leaves the rest for you to confirm.
How to catch a short number before you publish
- Read the 'Number inside the link' line and count the digits. Saudi and Emirati mobiles have 12; Kuwaiti, Qatari, Bahraini and Omani numbers have 11.
- Compare the last four digits with the original. That catches a missing or swapped digit in a second.
- Press 'Open link' and make sure the chat belongs to the right person. The tool cannot know whether the number exists or is on WhatsApp; only a test tells you.
Common questions
My number is right but the tool says it is too long. Why?
The country code is probably doubled: you picked it from the list and it was also typed at the start of the number. Switch to 'The number I type includes the country code', or delete the code from the box.
Does 'too short' mean the number does not exist?
It only means there are fewer digits than any international number can have. The tool knows nothing about whether the number itself exists.
