Q: My payment method is declined, and I can't enter other credit card number(it askes for validation) I've tried to change all nformation but it won't help, please help me

Hello jumanjet,

Thanks for the question, and welcome to Apple Support Communities.

I understand you are having issues adding payment information to your account.

If your account information does not match your credit card, you may get a message stating "The credit card was declined."

To expand on the above, your billing name or address may not match the address listed on your credit card statement. Any discrepancy in punctuation, abbreviation, or capitalization can cause errors, which might prevent you from purchasing from the iTunes Store. If you moved, or if your zip code changed recently, ask your credit card company to make sure their records are up to date and match exactly what you are entering as your billing information.
