Here are a few.
Let online retailers save your credit-card number Almost every store selling things online, from Amazon to your local stops, will offer to save your credit-card number so you won't have to type it in next time.
"It is convenient, but also puts you in jeopardy if they are hacked," said Steven J.J. Weisman, a Boston-area lawyer and college professor at Bentley University in Waltham, Mass. "And they will be hacked."
Don't be among the victims the next time a huge data breach happens. Decline the online retailers' offers, and type in your credit-card number every time.
Leave outgoing mail in your mailbox It's convenient to leave outgoing mail in your mailbox for the mail carrier to pick up. It's also convenient for identity thieves, who raid residential mailboxes looking for bill payments. After all, your personal checks are a jackpot of information.
Do the smart thing — drop off the mail in an official mailbox or take it to a post office.
Throw away mail, checks and financial documents intact Thieves are not above going through your trash hoping they'll find your full name and address, bank receipts, credit card statements or even canceled or voided checks.
Do the smart thing: Tear up anything with your name on it, and use a shredder for any document with financial information.
Access the Internet over public or insecure Wi-Fi networks "While it may be convenient to sip on a latte at Starbucks while reviewing your online bank account, public Wi-Fi is a feeding ground for identity thieves," Kelly said.
Similarly dangerous are open Wi-Fi networks in parks, airports, shopping malls, museums and libraries.
Protect yourself from Wi-Fi snoops by installing virtual private network (VPN) software, which will encrypt all Internet traffic on your laptop, smartphone or tablet.
Carry your Social Security card in your wallet If your wallet is stolen with your Social Security card in it, the thief won't just have your money, your driver's license and your credit cards — he'll also have your identity.
Writing down the number on a piece of paper in your wallet is just as risky, as is storing the number on your cellphone. (Stolen cellphones, especially smartphones loaded up with social media and online banking apps, are bonanzas for identity thieves.)
It's better to memorize your Social Security number, and to store the card in a locked safe or safe-deposit box.
Similarly, check other ID cards — Medicare cards, for example — to make sure they don't include your Social Security number. If they do, toss those in the safe as well.
Post personal information on social media The more personal details you post on a social media site, the easier you make it for a thief to steal your identity.
Think about your Facebook profile, for instance. Do you list your full birth date and year, as well as your childhood hometown? What about your parents' full names?
If so, you've just given a thief enough information to take over your identity without him having to break a sweat.
Give your personal information to people who call or email you
That nice-sounding lady calling from the bank says she needs your
account number. That official-looking email message from the IRS says
the agency needs your Social Security number — won't you please click on
this link to do so?Don't believe them. Organizations dealing with personally identifiable information, especially financial information, rarely send emails or make unsolicited calls.
Don't give your personal information, including credit-card numbers or Social Security numbers, to anyone calling you on the phone or sending unsolicited email messages.
You have no way of knowing whether or not that caller is legitimate, or whether than email message came from the purported sender.
If you feel you absolutely must respond, call the institution in question — and make sure you get its number from a phone book.
Things that make it easier for thieves to steal someone identities.
