In Three Days of the Condor, there's a scene where Robert Redford's character calls someone on the phone and requests a "CNA". Does anyone know what CNA stands for in this context?

    WOMAN'S VOICE

    (FILTER)

    CNA, Mrs. Coleman speaking.

    TURNER

    (into test-set)

    This is Harold Thomas, Mrs. Coleman,

    Customer Service.  CNA on 202 555-7389,

    please.

(Here's a transcript of the scene in question: http://www.cswap.com/1975/Three_Days_of_the_Condor/cap/en/25fps/a/01_25)

Relevant extract of the script:

Customer service, requesting a CNA...

on 202-227-0098.

One moment, please.

That would be a Mr. Leonard Atwood.

365 Mackenzie Place.

Chevy Chase, Maryland.

It seems fairly apparent that this stands for

Customer Name and Address

Since that's the context of the scene.
