How to Look Up YouTube Channel IDs in Bulk

Looking up Channel IDs one by one is fine for a handful of channels. For dozens or hundreds, you need a bulk approach. Here are the best methods for bulk YouTube Channel ID lookup.

When You Need Bulk Channel ID Lookup

You have a list of YouTube channels and need all their Channel IDs. Common scenarios:

• Building a competitor monitoring dashboard
• Setting up a YouTube Data API integration for client channels
• Doing influencer research across a large channel list
• Populating an analytics tool that requires Channel IDs
• Creating a YouTube automation with n8n or Make

Method 1 — channelid.app Bulk Lookup

The fastest option with no setup: channelid.app supports bulk input.

1. Go to channelid.app
2. Paste multiple YouTube channel URLs — one per line
3. Click "Get Channel IDs"
4. Download the results as CSV

Works with any URL format: @handle, /channel/, /c/, /user/. No API key required.

Best for: One-time bulk lookups, non-technical users, or when you need results fast.

Method 2 — YouTube Data API (Batch Requests)

If you have a list of Channel IDs and need to verify or enrich them, the YouTube Data API lets you batch up to 50 IDs per request.

GET https://www.googleapis.com/youtube/v3/channels
  ?part=snippet,statistics
  &id=UC1xxxxx,UC2xxxxx,UC3xxxxx
  &key=YOUR_API_KEY

At 1 quota unit per call, you can look up 50 channels for 1 unit — extremely efficient.

Limitation: This only works when you already have Channel IDs. For resolving URLs or handles to IDs, use Method 1 or Method 3.

Method 3 — Python Script for CSV Input

For recurring bulk lookups integrated into a pipeline:

Input file (channels.csv):

name,url
MKBHD,https://youtube.com/@mkbhd
Linus Tech Tips,https://youtube.com/@linustechtips
Kurzgesagt,https://youtube.com/@kurzgesagt

bulk_channel_ids.py:

import csv
import re
import time
import requests

API_KEY = "your_api_key_here"
BASE_URL = "https://www.googleapis.com/youtube/v3/channels"

def resolve_url(url: str) -> str | None:
    url = url.strip()

    m = re.search(r"youtube\.com/channel/(UC[a-zA-Z0-9_-]{22})", url)
    if m:
        return m.group(1)

    m = re.search(r"youtube\.com/(@[\w.-]+)", url)
    if m:
        r = requests.get(BASE_URL, params={"part": "id", "forHandle": m.group(1), "key": API_KEY})
        items = r.json().get("items", [])
        return items[0]["id"] if items else None

    m = re.search(r"youtube\.com/user/([\w-]+)", url)
    if m:
        r = requests.get(BASE_URL, params={"part": "id", "forUsername": m.group(1), "key": API_KEY})
        items = r.json().get("items", [])
        return items[0]["id"] if items else None

    return None

def bulk_lookup(input_csv: str, output_csv: str):
    results = []
    with open(input_csv, newline="", encoding="utf-8") as f:
        for row in csv.DictReader(f):
            url = row.get("url", "")
            channel_id = resolve_url(url)
            results.append({**row, "channel_id": channel_id or "NOT_FOUND"})
            print(f"{row.get('name', url)}: {channel_id}")
            time.sleep(0.3)

    with open(output_csv, "w", newline="", encoding="utf-8") as f:
        writer = csv.DictWriter(f, fieldnames=results[0].keys())
        writer.writeheader()
        writer.writerows(results)
    print(f"Done. {len(results)} channels written to {output_csv}")

bulk_lookup("channels.csv", "channels_with_ids.csv")

Method 4 — Google Sheets + Apps Script (No-Code)

1. Open your Google Sheet
2. Go to Extensions → Apps Script
3. Add this function:

function getChannelId(handle) {
  const apiKey = "your_api_key_here";
  const url = `https://www.googleapis.com/youtube/v3/channels?part=id&forHandle=${handle}&key=${apiKey}`;
  const response = UrlFetchApp.fetch(url);
  const data = JSON.parse(response.getContentText());
  return data.items?.[0]?.id ?? "NOT_FOUND";
}

1. In your sheet, use: =getChannelId("@mkbhd")

Quota Planning for Large Lists

The YouTube Data API gives 10,000 units/day free. channels.list?part=id costs 1 unit per call.

Key optimization: /channel/UCxxxxxx URLs require zero API calls — the ID is already in the URL.

Handling NOT_FOUND Results

Common causes: 1. Deleted channel — no longer exists 2. /c/ custom URL — API cannot resolve these directly 3. Typo in URL — check for extra spaces

For /c/ URLs: open in browser to see the /channel/UCxxxxxx redirect, or paste into channelid.app.

Summary

For most users: paste your list into channelid.app. For recurring bulk lookups, use the Python script. Cache everything — Channel IDs are permanent.
