A nonprofit organization using NPSP does a lot of mailings and wants to ensure states...

Enabling State and Country Picklists in Salesforce can improve data consistency and accuracy for address fields. However, there are specific considerations when using them with NPSP:

NPSP Data Import Object Doesn't Support State and Country Abbreviations in Picklist Form:

The NPSP Data Import object does not natively support state and country abbreviations in picklist form. This means that data imports using this object will require additional handling to map state and country values correctly.

Predefined State and Country Abbreviations on Address Records Must Be Used:

When using State and Country Picklists, predefined state and country abbreviations must be used. This ensures consistency and compatibility with Salesforce’s standard address fields.

If your current data uses different formats (e.g., full names or alternative abbreviations), you will need to standardize these before importing or entering data.

Consideration for Existing Data:

If enabling State and Country Picklists for the first time, review and clean existing data to match the picklist values.

Use data tools to update existing records with the correct state and country abbreviations to ensure smooth transition and consistency.

By understanding these considerations and preparing your data accordingly, you can successfully implement State and Country Picklists in NPSP.
