How to avoid “silly” mistakes with telephone numbers in Part 1 IELTS listening

The primary objective of this lesson involves preventing careless errors in IELTS Listening Part 1.

For candidates targeting a 6.5 band score or higher, achieving full marks (10/10) in Part 1 becomes crucial – subsequent sections (2,3,4) progressively increase in difficulty. Nevertheless, unexpected errors may occur in this section without proper preparation.

When processing telephone numbers during the listening test, note these key factors: 
The digit 0 is consistently spoken as “oh” rather than “zero” 
Repeated digits use “double” (e.g., “double 7” for 77) 
Numbers are delivered in clusters of 2-3 digits rather than individually. For example, 13554684616 would be articulated as “13 – double 5 – 468 – 46 – 16”
