Social Security Card
If your Social Security card falls into the wrong hands, someone could open a credit card, apply for a loan, file for tax returns, or even buy a car with the information. Identity theft springing from a stolen social security card carried in a wallet or purse is among the most common ways people become victims. With that Social Security number and little else, a criminal can take over your identity, open new accounts in your name, work under your name, create new drivers licenses or state ids in other states, and more. Unless you have need of your Social Security card THAT DAY, do not carry your Social Security card around in your purse or wallet.
This document, because it is government-issued, is also useful in acquiring a new Social Security card, driver's license or state ID card, and can be used as an identifying document in acquiring a loan or opening a new credit account.
Don’t carry any type of pin number, pass code or password on any piece of paper in your wallet. If you absolutely can't remember important codes or words, store them digitally on a password-protected phone under a less obvious name (for example, the name of an old pet, a personal nickname, etc.).
Checkbook and Account/Routing Numbers
Your checkbook has both your account number and routing number printed on it, as well as your address. If you know you're going to need to write a check that day, take only the number of checks you think you need out of your book and take it with you. Unlike the loss of a credit card, simply cancelling the card will not prevent a thief with access to your account numbers from making use of your account. You will have to close the account and open a new one. Also, do not keep any of your account and routing numbers written down in your wallet. These number sequences can be identifiable to thieves.
