What Does Microsoft Access Runtime Error 6 Overflow Mean?

When runtime error 6 overflow occurs in Microsoft Access, it means that a value that is assigned in a VBA code for calculation is too large or a calculation has resulted in a value that is too large to be stored in the field it was intended for.

However, this error message is triggered due to various reasons. Some of the most common causes are as follows:

  1. Mismatch Data Type– It is the foremost reason for this Access error. If you are attempting to store a value in a field that exceeds the limits of the Integer data type (the range is: -32,768 to 32,767), you can face an overflow error.
  2. Database Corruption– The corrupt Access database file can result in various unpredicted errors, including run-time error 6 Overflow.
  3. Mathematical Operations– If you are multiplying two large numbers, the result value may be too large for a field or an Integer, it can cause this error message in the Access database.
  4. VBA Code– Validate your VBA code for any expressions, calculations, or assignments that could possibly result in the values exceeding a data type’s limits.
  5. External Data Sources– If you are importing/linking data from the external sources, like MS Excel or MS SQL Server that is incompatible with your Access database, this can trigger error 6 Overflow.
  6. Outdated Version– Using an outdated version of MS Access or Microsoft Office suite can lead to such errors.
