To locate the paper money serial number, firstly, check the front of the bill and look for a series of numbers printed in black ink. These numbers will vary depending on the denomination of the bill, but typically they are located near the top right corner. Once you have found the serial number, verify it with the corresponding numbers printed on the back of the bill. These numbers should match exactly and usually run horizontally across the bill. If they do not match, it is possible that the bill is counterfeit and should be reported immediately.
## Identifying the Serial Number Location
### Paper Currency of the United States
Locate the serial number on the front of the bill, typically below the imagery. It consists of 11 characters, a combination of letters and numbers, separated by a space.
### Currency Notes from Other Countries
The serial number’s placement varies depending on the issuing country. Generally:
- European Union banknotes: Found in the upper right corner on the front
- British banknotes: Located at the top and bottom of the note, on either side of the Sovereign’s profile
- Canadian banknotes: Printed twice, once vertically on the left side and again horizontally on the right
### Serial Number Structure
| Character | Description |
|---|---|
| First Letter | Identifies the Treasury District where the bill was printed |
| Second Letter | Indicates the Federal Reserve Bank responsible for distributing the bill |
| Third, Fourth, Fifth Characters | Number sequence within the printing batch |
| Sixth, Seventh Characters | Year the bill was printed |
| Eighth Character | Month the bill was printed (A-L) |
| Ninth, Tenth, Eleventh Characters | Unique number within the printing run |
Checking the Banknote for Authenticity
Before locating the serial number, it’s crucial to ensure the authenticity of the banknote. Here are some security features to check:
- Watermarks: Hold the banknote up to a light source. You should see a faint, translucent image in the blank area.
- Security Thread: Look for a thin, metallic thread embedded in the paper. It changes color or appears broken when tilted.
- Raised Elements: Run your finger over the printed areas. You should feel a slight bump on genuine banknotes.
- Hologram: Tilt the banknote to observe a three-dimensional or moving image.
- Ultraviolet Ink: Some elements on the banknote, such as the serial number and security thread, glow under ultraviolet light.
If the banknote passes these checks, proceed to locate the serial number.
Locating the Serial Number
| Banknote | Serial Number Location |
|---|---|
| US Dollar | Lower left and upper right corners |
| Euro | Upper left and lower right corners |
| British Pound | Upper right corner (new banknote) or lower left corner (old banknote) |
| Indian Rupee | Upper left corner (new banknote) or lower right corner (old banknote) |
| Chinese Yuan | Upper left and lower right corners |
The serial number may be printed in red, blue, or another color for security reasons. It typically consists of a combination of numbers and letters, separated by spaces or hyphens.
