Name

Names are at the heart of every contact record—yet they're often incomplete, misspelled, or reversed. Delpha's Name Validator helps you detect, normalize, and correct person names to ensure consistent, high-quality identity data across your systems.

Each input is evaluated through several smart checks:

• Completeness: Measures whether both first name and last name are present, returning individual scores for each.

• Validity: Confirms if the given names exist in trusted linguistic databases.

• Consistency: Compares the original input to its normalized form (capitalization, spacing, hyphenation, etc.).

• Misspelled: Detects potential typos and suggests the closest valid alternatives.

• Reversed: Identifies when first name and last name appear swapped based on statistical likelihoods.

The API returns a normalized version of the name, along with these detailed quality indicators. When needed, it also proposes gentle corrections—like fixing a misspelling or switching first and last names—always preserving the user's intended identity.

With Name Validator, your contact data stays clean, standardized, and ready for reliable engagement.
