The Cold Calling achievement in SILENT HILL: Townfall asks you to dial a set of hidden phone numbers scattered across the story. The good news is that you do not have to read a note or hear a character say a number before using it. Every code works the moment you punch it in, so long as you have already reached the chapter where that number becomes relevant.
That last detail is the only real catch. If you try a Part 3 number while still in Part 1, the game will not let you place the call. Work through the chapter first, then dial.
Editor Warning: You cannot rush this achievement on a fresh save by entering every code at the first phone booth. Numbers from later parts are locked until the story catches up. Save yourself a headache and dial each one as you progress.
Part 1 Phone Numbers
All four numbers in this section come from the early stretch of the game. Three of them are handed to you at the very first phone booth you encounter.
| Number | Contact | How to Unlock |
|---|---|---|
| 900 | Emergency Services | Learned at the first phone booth. |
| 010 | Operator | Learned at the first phone booth. |
| 100 | Save Yourself | Learned at the first phone booth. |
| 4960244 | The Haldane Hotel | Read the bottom of the Room Service Card in Room 204, or any other Haldane Hotel note you find. |
| 4960496 | Tourist Center | Flip over the map. |
| 4960842 | Unknown | After returning from the Unknown Otherworld, enter the first three digits 496 to reveal the rest of the number. |
The 4960842 entry is the one most players miss. The game only fills in the final digits once you are back from the Otherworld segment, so if the full code is not showing, you are not far enough yet.
Part 2 Phone Numbers
This batch is tied to your client’s neighborhood and the surrounding district. None of them require backtracking if you check documents as you go.
- 01632960595 — St. Amelia District Council. Read the Water Warning Document.
- 4960103 — Zoe Ellis. When you enter your client’s house, open the case sitting next to the phone.
- 4960556 — Dr. Glenn. Check the document in front of the Medical Center. It is titled Medical Security Note.
If you are chasing the All Collectibles Locations alongside this achievement, the Medical Security Note and the case by the phone are both easy to walk past. Grab them on your first visit so you do not have to loop back.
Part 3 Phone Numbers
Only one number appears in this section, and it is not written down anywhere. Dr. Glenn gives it to you directly over the intercom after you finish the dosage step.
- 5353 — Hospital Storage. Provided by Dr. Glenn through the intercom once the dosage step is complete.
Editor Warning: Listen for the intercom line after the dosage puzzle. The number is spoken aloud only once, and there is no note to fall back on. Write it down if you are playing with subtitles off.
Part 4 Phone Numbers
The final set closes out the achievement. Two of these require you to interact with objects before the number is available.
| Number | Contact | How to Unlock |
|---|---|---|
| 946 | WHO Dial Back Service | Read the Information Poster inside the phone booth. |
| 4960112 | Unknown | Watch the cutscene at the phone booth, then call 496 to receive the new number. |
| 4960993 | CEG Lockers | Enter the CEG Lockers, find the barcode, then look at the top of the document. |
The 4960112 code follows the same pattern as the earlier Unknown entry. Call the partial number 496 after the cutscene plays out, and the game hands you the rest.
Order of Operations for the Full Set
You need to dial every number listed above to unlock Cold Calling. Because later codes stay locked until their chapter arrives, the safest routine is to enter each one the moment you obtain it. Dial at the nearest phone booth, confirm the call connects, and move on. Following the chapter order above also keeps you on track for the 100% Achievement run, since several of these numbers sit next to missable documents and cases.
One last thing worth knowing: entering a code early does register as a valid call for the achievement, so there is no penalty for punching in a number as soon as it appears in your notes. The only numbers that stay dead are the ones from chapters you have not reached yet.
