Questions & Answers about zhè shì kèfúdiànhuà.

What does 这 mean here, and why is it translated as this?

这 means this.

In this sentence, 这 stands alone as a pronoun, so it means this or this thing:

• 这是客服电话。 = This is the customer service phone number.

If 这 comes before a noun, it usually works like this + noun, often with a measure word:

• 这个电话 = this phone
• 这个号码 = this number

But here, 这 is not directly modifying a noun. It is the subject of the sentence, so this is a natural translation.

Why is 是 used here?

是 is the verb to be in this sentence. It links 这 and 客服电话:

• 这 = this
• 是 = is
• 客服电话 = customer service phone number / customer service line

So the basic pattern is:

• A 是 B = A is B

This is one of the most common sentence patterns in Mandarin.

Examples:

• 这是老师。 = This is a teacher.
• 这是我的手机。 = This is my phone.

Do I need a measure word after ? Why not ?
