1. Your Cell phone manufacturer is different then your cell phone service. Your Cell Phone Service provider is not the manufacturer of your phone. Although it may seem a little confusing, Sprint, AT&T, Verizon, Alltel, Nextel, and the rest of the service providers do not manufacturer you cell phone.

2. Here is a short list of some of the major phone manufacturers:

Motorola
Samsung
Sanyo
Palm
Nokia
LG
Audiovox
Blackberry
HTC
Pantech
Sony Ericsson

3. Some Things to know about cell phone manufacturers:

Often times, a cell phone manufacturer will use a common prefix in their Manufacturer Part Numbers (MPN). Here are some examples of manufacturer prefixes:

Motorola: W, V, Z (Examples of Motorola Part numbers: W385, V3, Z6tv)

Samsung: SPH, SCH, SGH (Examples of Samsung MPN: SGH-T429, SPH-i325, SGH-X495)

Sanyo: SCP (Examples of Sanyo MPN: SCP-3200, SCP-6600)

Audiovox CDM (Examples of Audiovox MPN: CDM-8945) HTC: XV, PPC, P, S (Examples of HTC MPN: XV6900, PPC-6800, P4350, S620)

Sony Ericsson:K, W, Z (Examples of Sony Ericsson MPN: K750, W580, Z525)

Although not every phone has a prefix to its MPN, this can be very helpful when locating your MPN on your phone.

Locating the Manufactuer Part Number on a phone:

Turn off your cell phone and remove the back cover/battery. Find the Barcode on the inside of your phone (not the barcode on the battery)that may be labeled IMEI, DEC, or ESN. The MPN should be found right above this bar code as show in the pictures below:
