Checking 101

What is a Checking Account?

A checking account gets its name from the act of writing a check to transfer money. It’s the most common type of bank account and is distinct from other account types, such as money market or certificate accounts, in that there are practically no restrictions on how often you may access your funds. While writing a check is the method of transferring money from which this account was named, there are now many other options to transfer money, such as using online or mobile banking or a debit card.

Routing, Account and Check Numbers: What’s the Difference?

A Routing Number (or ABA Routing Number) serves as a financial institution’s identification number and can be found on the lower left side of your checks, as seen below. SDCCU’s ABA Routing Number is 322281617.

Similarly, your checking account number uniquely identifies your checking account. Your checking account number is the lower middle number on your checks, shown below.

The check number is seen at the bottom right and the upper right corner of your checks.

Choosing a Checking Account

SDCCU offers a few options for checking accounts, depending on your needs. To understand the complete range of services that may incur fees, it’s recommended that you read our Consumer Services Fee Schedule.

  • FREE Checking with eStatements – As indicated in the name, this account incurs no monthly service fees when you sign up to receive eStatements. An eStatement is an electronic version of your statement, which can be viewed securely through Internet Branch online banking at sdccu.com. There is no minimum balance requirement, other than an opening deposit of $25.
  • Classic Checking – A classic checking account is ideal for those wanting to earn monthly dividends on their balance. Dividends are similar to interest paid by banks. Dividends may be paid monthly with an average daily balance of $1,500 or more. See our current checking account rates to view Classic Checking dividend rates. The monthly fee of $5 is waived with direct deposit ($100 minimum per pay period), $2,500 or more combined average daily savings balance or $1,000 or more average daily checking balance. The minimum opening deposit is $25.
  • High-Yield Checking – A high-yield checking account is ideal for those wanting to earn higher returns on their balance. This personal checking account earns competitive dividends based on the average daily balance. Check out our current checking account rates to view High-Yield Checking dividend rates. Added benefits include higher potential dividends than classic checking and a FREE first box of corporate image checks. The monthly fee of $15 is waived with an average daily balance of $25,000 or more. The minimum opening deposit is $5,000.
  • teenFIRST® Checking – The teenFIRST account is for members 16 or 17 years of age with a valid ID. While the teen will be the primary member on the account, their parent or guardian must be a Joint Owner on the account until the teen turns 18. Once they turn 18, the teenFIRST checking account automatically converts to a FREE Checking with eStatements account and is free when enrolled in eStatements. Otherwise, a nominal monthly fee of $2 applies.

Keep a Cushion if You Can

SDCCU offers a variety of overdraft protection options, but it’s always best to keep a cushion in your checking account. Some purchases may take a while to post to your account, so keeping a cushion can help you avoid overdrawing your account if you lose track of exactly what was spent.

Track Your Spending

It’s best to set up account alerts to send you automated, real-time email or text messages when your account drops below a certain amount. If you still write checks, make sure to keep records in your checkbook each time you write a check, deduct it from your balance and monitor your account to see when it clears.

Protect Your Data
