I need REGEXP for alpha Numeric zip code, which contains minimum 3 & maximum 10 values

Question

I need REGEXP for alpha Numeric zip code, which contains minimum 3 & maximum 10 values.

Invalid inputs are: AAAAA, A1, AA, 12, 2A
Valid inputs are: 123456, 123, A1234, A12, A12A, A9A

This is the regex I'm currently using:

/(^[A-z0-9]\d{3,10})+$/

It doesn't allow to specify only digits like this 12345 but input like A123 matches correctly.

I'm not quite following what you're asking. If you just want to match 3-10 alphanumeric characters, then use `/^[A-z0-9]{3,10}$/`. — Bradley Garagan, May 18 '15 at 12:19
This question is pretty confusing as written. Could you maybe write example inputs and outputs that do not work as expected? — Anonymous, May 18 '15 at 12:24
Your regex currently says allow a number or letter as the first character, then allow 3-10 numbers. You state `it is not allowing only number`; so get ride of `[A-z0-9]`. I'm also not sure what the trailing `+` is for at the end of the expression. — chris85, May 18 '15 at 12:24
i want input like this 123456, A12A, A12. those are valid input & also input must be in between min 3 & max 10 — Mahesh Kalyankar, May 18 '15 at 12:55
if i am giving only numbers like 12345 it is showing error msg enter valid zip code — Mahesh Kalyankar, May 18 '15 at 12:56

The question is not completely clear. If you mean that you can use between 3 and 10 characters, and these characters can be alphanumerical characters (digits and [A-Za-z]), you can use:

/^(?=.*\d.*)[A-Za-z0-9]{3,10}$/

regex101 demo.

The regex works as follows:

^[A-Za-z0-9]{3,10}$ says the regex consists out of 3 to 10 characters that can be digits and/or A-Z/a-z.
The lookahead (?=.*\d.*) enfoces that the string contains at least one digit somewhere in the string.

@MaheshKalyankar: as commented before, your question is very unclear, please reformulate it. – Willem Van Onsem May 18 '15 at 13:02
@MaheshKalyankar: and furthermore all the provided inputs are validated by the regex... Please give a counterexample. – Willem Van Onsem May 18 '15 at 13:04
invalid- AAAAA, A1, AA, 12, 2A, – Mahesh Kalyankar May 18 '15 at 13:09
valid- A1A, A12, 21A,123,123456, 2A1 – Mahesh Kalyankar May 18 '15 at 13:10
@MaheshKalyankar: so there must be at least digit in the string? – Willem Van Onsem May 18 '15 at 13:11
yes only digit is valid but only alphabet is not valid for my purpose – Mahesh Kalyankar May 18 '15 at 13:13
@MaheshKalyankar: see updated answer, all your examples match/don't match with regex101... – Willem Van Onsem May 18 '15 at 13:14
@MaheshKalyankar: is lowercase enabled? – Willem Van Onsem May 18 '15 at 13:15
