The model number for a phone that I am wanting to get is PAAE0007US, is this model compatible with republic wireless?
Yes, it is supported
Two great references provided by the community and found in the Tips & Tricks
Republic now supports the Moto G6. Once again, we have the fun on multiple model numbers. The Motorola Model number is XT1925-6. In some cases you may see the phone advertised by its part number. In this case, the phone will be listed as PAAE0000US, PAAE0002US or PAAE0007US. These are the same phone (differences may be Amazon Prime Exclusive version and/or color) and no matter which way it is listed, it will work with Republic.
