I am analyzing our company's telephone call records in raw text format - all
I have is the telephone number that was dialed by the caller. With the help
of a master reference list I created listing all dialing patterns possible
and the related location name for each, I am trying to associate a
country/city/mobile description to each phone call record to know the
geographic location called. What I would want to do is find the location
name in Sheet 2 for each call record in Sheet 1 using the dialing pattern
that matches it best (from left-most to right-most text position in Sheet 1).

Here's an example:
Sheet 1 - Our call records
Call #1: 52512346789
Call #2: 33189895656
Call #3: 966512345555
Call #4: 33845457777
Call #5: 33485556666

Sheet 2 - My reference list (in numerical order per country)
-start of file-
1 - USA
1212 - USA (New York)
....
33 - France
331 - France (Paris)
336 - France (mobile)
....
52 - Mexico
525 - Mexico (Mexico City)
....
966 - Saudi Arabia
9965 - Saudi Arabia (mobile)
....
998 - Uzbekistan
-end of file-

Sheet 3 - My desired result
Call #1: 52512346789 - Mexico (Mexico City)
Call #2: 33189895656 - France (Paris)
Call #3: 966512345555 - Saudi Arabia (mobile)
Call #4: 33845457777 - France
Call #5: 33485556666 - France

Appreciate any info you can share.
