Phone Numbers in Pokémon Crystal can be divided into two groups by their acquisition: Trainers and Non-Trainers.
Non-Trainers give you their phone number at a certain point in the game or when some conditions are met. Since they’re not battleable trainers, you don’t need to fight them to get their numbers
|Non-Trainer Phone Numbers|
|NPC||Acquisition||Uses & Notes|
|Mom||Registered automatically at the beginning of the game.||
|Prof. Elm||Registered automatically at the beginning of the game.||
|Bill||Given by Bill’s Brother at his residence in Goldenrod City.||
|Buena||Given by Buena after accumulating 30 Blue Card points from her Radio Show.||
On the other hand, Trainers only give you their phone number after beating them in a Pokémon Battle.
After the battle, you need to talk to them again to register their contact.
Most trainers will call you to challenge you to a rematch. A few of them also have secondary functions, like sharing info about swarms or giving you valuable items.

Best Phone Numbers to Keep
Your PokéGear can only hold ten contacts at a time, and three of them are already taken up by Mom, Prof. Elm, and Bill. These numbers can’t be erased.
That leaves us with seven contacts to fill up.
With 25+ phone numbers in the game, choosing just seven is hard.
Here’s a list of ten suggestions to consider keeping in your contacts, at least for a little while during your adventure:
|Best Trainer Phone Numbers|
|NPC||Location||Why You Should Keep It|
|Camper Todd||Route 34||It’s the only way to know a Rooftop Sale is underway.|
|Picnicker Gina||Route 34||Free Leaf Stones. Leaf Stones are needed by Gloom, Weepinbell, and Exeggcute to evolve.|
|Schoolboy Alan||Route 36||Free Fire Stones. Fire Stones are needed by Vulpix, Growlithe, and Eevee to evolve.|
|PokéFan Derek||Route 39||Free Nuggets. Nuggets sell for a lot of money (5,000 PokéDollars).|
|PokéFan Beverly||National Park||Free Nuggets. Nuggets sell for a lot of money (5,000 PokéDollars).|
|Fisher Tully||Route 42||Free Water Stones. Water Stones are needed by Poliwhirl, Shellder, Staryu, and Eevee to evolve.|
|Picnicker Tiffany||Route 43||Free Pink Bows. There are many strong Normal-type Pokémon in the game.
Getting multiple Pink Bows for free can help you power-up some of them and strengthen your team.

|Bird Keeper Jose||Route 27||Free Star Pieces. Star Pieces sell for a lot of money (5,000 PokéDollars).|

It’s the ultimate badge of honor, and her phone calls are some of the most entertaining.
You can also learn some useful tips by calling her.
Erasing PokéGear Contacts
You can erase phone numbers by going into [START > PokéGear > Phone] and choosing the contact you no longer need. Then, select Delete from the pop-up menu.
You can recover these phone numbers later by talking to the NPC with at least one free slot in your PokéGear memory.
