The Difficulty of Identifying Customers
Given two sets of data that differ slightly, perhaps with a nickname ("Barb" instead of "Barbara") or with a cell-phone number, how can a computer distinguish between different aspects of the same customer and two distinct individuals?
In the larger sense, customer data can become very complex; for example, it may require anywhere from six to twelve or more fields to represent just a personal name. For example, some typical fields associated with a customer "name" may include:
- Name prefix (Mr., Mrs., Dr., Captain)
- Given name (a.k.a. "first name" or "Christian name" in some cultures)
- Family name
- Middle name(s)
- Name Suffix (Jr., Sr., II, III)
- Initials
- Nickname
- Maiden name
- Married name
- Professional title
- Academic title
Address entries have their own complexities (for example: primary address number, pre-directional (N, S, E, W,) street name, street suffix, post-directional, secondary identifier (building, suite, apt,) secondary number, city, state, ZIP, and ZIP+4(R))
Add in phone numbers, social security numbers, email addresses, tracking (customer number, account number), relationship, risk-level, purchase history, service history, demographic, socio-economic, lifestyle, consumer-behavior segmentation and privacy preferences, just to name a few.
This information varies constantly, whether due to changes, entry-errors, corrections, or fraud. And many medium-to-large organizations store this sort of data in several different places: different departments, different locations, in different formats, etc.

Famous quotes containing the words difficulty and/or identifying:
“The great difficulty is first to win a reputation; the next to keep it while you live; and the next to preserve it after you die, when affection and interest are over, and nothing but sterling excellence can preserve your name. Never suffer youth to be an excuse for inadequacy, nor age and fame to be an excuse for indolence.”
—Benjamin Haydon (17861846)
“And the serial continues:
Pain, expiation, delight, more pain,
A frieze that lengthens continually, in the lucky way
Friezes do, and no plot is produced,
Nothing you could hang an identifying question on.”
—John Ashbery (b. 1927)
