Polar code is the first channel code proven to reach Shannon capacity and is proposed for use in high-speed data communication system. However, the use of independent Polar code with a finite number of bits shows poor performance compared to earlier codes, namely Turbo and Tail-biting Convolutional codes. In this study, the Polar code is equipped with the Cyclic Redundancy Check (CRC-11) code and the Succesive Cancellation List (SCL) decoder according to the recommendations in the 5G System Specifications. The code performance is analyzed for a limited number of bits, using BLER and Es/N0 as performance parameters. The number of bits of information encoded in this study were 32 and 64 bits, while the number of bits in the codeword were 432, 864, and 1728 bits, so that the code performance for short blocks of information and codewords can be observed. The list sizes on the decoder are 1, 2, and 4. The simulation results show that the simulated code allows communication to take place with the value of Es / N0 in the range -11.5 dB to 1.8 dB to achieve Block Error Rate (BLER) 10- 2. This shows that a Polar code equipped with a CRC code and an SCL decoder has a good performance for a limited number of bits.
