As soon as you are 18, you can start building up your credit by applying for a credit card. You would need a parent’s signature.

You don’t "prove" your credit, because they can look it up.

You must be 18 to sign contracts. No one will extend credit to you until you are legally liable for the contract terms. When you do turn 18, you will have problems getting a credit card. The new law requires people under 21 to provide proof of sufficient income to qualify for credit cards or have a parent co-sign. You will probably have to start with a secured card.

At this point, open a bank account and keep it in good standing. You will be more likely to get that bank to give you a credit card when you turn 18, if you have a history with that bank.

A credit card is a good way to build ur credit… yes u do have to be 18 to apply but u can start before if u can get one of ur parents to cosign a credit card for u… this way, by the time u are 18 ull already have credit established. ur credit is very important in purchasing big items such as a car or renting an apt so be on top of ur payment. the smartest way to use ur card if u dont really want to buy much is to use it for purchases over $20 and pay it off as soon as u get ur statement. This is something i found while browsing for a new credit card… they got some good recommendation on which card to apply for

ask your mum to add you as a authorized user

if your 18 then you can get a secured card

i suggest going with Wells Fargo bank as they have the lowest yearly fees out of all the main banks

https://www.wellsfargo.com/credit_cards/secured/

the New Federal rules that were passed in February. Does Not apply to Secured Cards as it’s backed by the security deposit

also the bank may chose to give a unsecured card ( odds are very slim with no credit)
