WHERE TO check serial number on dollar bill

The serial number on a U.S. dollar bill is on the front of the note, usually in the upper right area and also repeated in the lower left or lower right area depending on the design. It’s the string of letters and numbers printed in green or black that uniquely identifies the bill.

Quick Scoop

For most modern U.S. bills, check the front side near George Washington’s portrait on a $1 bill, or near the main portrait on higher denominations. The serial number helps identify the note’s series and issuing Federal Reserve Bank, and every note has one.

What it looks like

A serial number usually includes:

• A letter at the start.
• Eight digits in the middle.
• A letter at the end on many bills, especially higher denominations.

Where to find it

• Front of the bill.
• Near the top right and/or lower opposite corner.
• Printed in the same color family as other Treasury markings, not as part of the portrait or border art.

Extra note

If you’re checking because you think the bill might be collectible, the serial number is the right place to start, but rarity also depends on the pattern, condition, and denomination.
